4.3.6-1 Method summary
According to the relationship between liquid surface tension and micropores, it is approximately calculated through bubble pressure test. 4.3.6.2 Sampling and processing
Perform according to the provisions of GB450 and GB10739.
4.3.6.3 Instrument installation and inspection
The instrument should be placed on a stable test bench and kept horizontal. Check whether the needle valve is flexible and whether the water level of the ""-shaped tube pressure gauge is at zero. Check whether the joints of each part of the instrument are sealed. 4.3.6.4 Sample preparation
Evenly cut 5 discs with a diameter of 46mm along the horizontal paper web. 4.3.6.5 Test steps
a And start compressed air. Put the sample on the base, press the gasket, and then tighten the screw. Close the outflow valve at the lower end of the base and fill the nut with isocyanate.
h, slowly raise the meter valve, let compressed air in from below the filter paper, and gradually increase the gas pressure until the first bubble appears on the surface of the isopropanol, and record the gas force at that time (the pressure difference of the water column in the "U" tube. c, close the needle valve, open the outflow cabinet, smash the paper sample, put the isopropanol into the beaker, measure the temperature, and recycle the isopropanol. Test 5 paper samples with the above force method and take the average pressure. 4.3.6.6 Calculate

4.4 Filtration performance test method
4.4.1 Drilling fluid preparation
Prepare drilling fluid with stable filtration loss range of 5~~100ml indoors or from 4000ml. 4.4.2 Filtration performance determination
4.4.2.11.TP filter paper is tested at room temperature and 0.7℃ using a normal temperature medium pressure filtration loss tester. MPa for measuring the filtration loss of drilling fluid for 30 minutes. HTP1 filter paper uses a high temperature and high pressure filtration loss meter to measure the filtration loss of drilling fluid for 30 minutes at 150℃ and 3.5MPa. 4.4.2.2 From a batch of products, randomly select 5 boxes and take two sheets from each box at different locations. Use the same drilling fluid and under exactly the same conditions to measure the filtration loss of drilling fluid 10 times. 4.4.2.3 Calculation
The relative average deviation of the filtration loss of LTP or HTP1 filter paper is calculated according to the following formula: a
Q×100
Wherein: X-relative average deviation of filtration loss, %; d-average deviation of filtration loss, ml;
---average filtration loss of filter paper, ml;
Wherein the average deviation of filtration loss d is calculated according to the formula: d
d= Q:—Q!
Where: di---the absolute value of the measurement deviation of a certain filtration loss, ml; Qi--the measurement value of a certain filtration loss, ml.
Among them, the average filtration loss of filter paper is calculated according to the following formula 1
Where: 10---the number of filter head measurements. 4.5 Test report
